Title: Going to the End of the Earth to Learn About the Beginning of the Universe

The cosmic microwave background (CMB) is revolutionizing our understanding of the Universe. The CMB is the most powerful piece of evidence that we live in a geometrically flat Universe, dominated by more »cold dark matter and dark energy. Even with this basic cosmological model established, there are still many outstanding questions: What is dark energy? What is the sum of the neutrino masses? Are there unknown particle species that we can detect cosmologically? Did Inflation happen? I will review the history of measurements of the CMB; what have they told us so far, and how the South Pole has developed into the premier site for observations of the CMB. Finally, I will discuss new measurements and cosmological results from the South Pole Telescope, a 10-meter diameter telescope that is making precision measurements of the temperature and polarization anisotropy of the CMB.« less
